Zao Snow Monsters: Frozen Giants on a Japanese Mountain
How to see the juhyo snow monsters of Mount Zao: when they form, riding the Zao Ropeway, the night light-up and getting there from Yamagata.
Quick answer
- What it is: fir trees on Mount Zao that freeze into huge white shapes called juhyo, or snow monsters.
- How they form: icy winds from Siberia coat the trees in frost and snow, layer by layer.
- Best time: usually late January to late February, with a wider season from late December to March.
- Getting up: the Zao Ropeway runs from Zao Onsen up to the snow monster fields.
- Time needed: half a day, plus time for an onsen in Zao Onsen village.
High on Mount Zao each winter, an army of ghostly figures appears. They are fir trees, coated so thickly in frost and snow by freezing winds that they turn into monsters, some taller than a house.
Why the snow monsters are a wonder
Juhyo form when cold, wet winds blow across the mountain from the Sea of Japan. Supercooled droplets freeze on contact with the trees, and snow builds up on the ice until the branches disappear.
Conditions have to be just right: cold enough for the frost to grow, but not so cold or dry that the snow will not stick. Only a few places in the world produce them on this scale.
Seeing them by ropeway
The Zao Ropeway climbs from Zao Onsen in two stages. The lower line reaches Juhyo Kogen, and the upper line rises to Jizo Sancho Station, close to the largest snow monsters.
At the top, a stone statue of Jizo, a Buddhist guardian, is often buried up to its neck in snow. On clear days you can see across the mountains of Yamagata.
Ways to see the snow monsters
| Option | What you get | Time (approx.) |
|---|---|---|
| Zao Ropeway (daytime) | Views over the snow monster fields from the top station | 2 hours |
| Night light-up | Snow monsters lit in colour on selected winter evenings | 1.5 hours |
| Snowcat tour | A guided ride through the juhyo fields in a snow vehicle | 1.5 hours |

| Zao Onsen | An acidic sulphur hot spring village at the base | 1 hour or more |
When to go
- Late January to February: the snow monsters are usually at their largest.
- Clear mornings: the best visibility, as cloud and blizzards often roll in later.
- Evenings: the ropeway runs night light-up sessions on selected dates in winter.
- Green season: in summer the trees look ordinary, but the Okama crater lake on the Miyagi side is a highlight.
Our tip: Dress as if for a polar expedition: thermal layers, waterproof boots, gloves and a face cover. Temperatures at the top can fall far below freezing, with strong winds.
Getting there
- From Tokyo: take the Yamagata Shinkansen to Yamagata Station, about 2.5 to 3 hours.
- From Yamagata Station: buses run to Zao Onsen bus terminal in about 40 minutes. The Zao Ropeway is a short walk away.
- Ropeway status: strong winds can stop the ropeway, so check the official Zao Ropeway site on the day.
Staying safe
- Stay on marked areas near the stations unless you are on a guided tour.
- Do not climb on or break the snow monsters.
- Check weather and ropeway status before you go, as services stop in strong winds.
- Wear proper winter footwear, as the paths at the top are icy.
